Crack WEP using BackTrack

Lifehacker wrote a guide for cracking a WiFi network’s WEP password using BackTrack. BackTrack is a Linux live CD used for security testing and comes with the tools needed to break WEP. Not just any wireless card will work for this; you need one that supports packet injection. The crack works by collecting legitimate packets then replaying them several times in order to generate data. They point out that this method can be hit-or-miss, especially if there are few other users on the network, as the crack requires authenticated packets. We covered cracking WEP before, but using BackTrack should smooth out compatibility issues.

If there are few users on the network and not many IVs are being captured, you can use an injecting attack to generate more. It’s been a while since I’ve reviewed it, but it really beats sitting around for an hour.

Please dont tell me that people havent already heard about this? Oh and just to point out backtrack aint essential. I mean aircrack-ng runs on many linux platforms the only advantage is for windows users who wanna try linus before making the right move ;)

btw what does backtrack help when your hardware is not supported with the drivers provided with it, or if you need to patch them to enable packet injection? I doubt you’d prefer BT3 or BT4 over any standard good linux distro anymore. Besides all software incluuded in BT is also abailable as .rpm or .deb for *real* linux. :D

Are you kidding, did hackaday really publish this. An article showing some of the new features of backtrack 3 would have been nice, but did you really have to spoon feed kiddies this info, if they are ready for it, they will learn it on their own. There are plenty of enough resources out there.

Sorry, not everyone is lucky enough to spend all their computer time developing the future like all the naggers on here. Some of us have to do other important work tha tdoesn’t require rewritting programs. Also, some of us do have to start somewhere when trying new ( to us ) things and any tutorial can be helpful.

Hi guys i might be a little late but wouldn’t it be possible to share gpu like folder at home to crack a wpa password? Just wandering if we could split the task the same way we spilt file on p2p sharing?
